Paper Abstract

A standardized metrics program was developed and implemented by Advanced Diagnostics, Inc. (ADI) to quantify Diffractive Energy Imaging (DEI) system performance. DEI is a medical imaging technology which uses primarily diffracted wave information obtained form passing ultrasound energy through the anatomy. The resulting real-time, large field-of-view, high-resolution images are currently undergoing clinical evaluation for detection and management of breast disease. This unique imaging modality required novel modifications to conventional measurement and evaluation tools. Measurement tools were developed and metrics procedures were standardized to ensure measurement accuracy and repeatability during performance testing. The system modulation transfer function, effective size of the field- of-view, spatial resolution across the effective field-of- view, contrast resolution, minimum detection, and field uniformity were quantified. Improved system metrics monitor improvements to DEI image quality and are supported through images of target standards and subjective validation using images of human anatomy.
